Regulated voltage converter circuit

Claim 1

DIRECT-CURRENT VOLTAGE CONVERTER APPARATUS COMPRISING AN INPUT TO WHICH A DIRECT-CURRENT VOLTAGE MAY BE APPLIED, AN OUTPUT INCLUDING A RECTIFIER-FILTER FOR PRODUCING A LOAD DIRECT-CURRENT VOLTAGE, AND A TRANSISTOR OSCILLATOR CONNECTED BETWEEN SAID INPUT AND SAID OUTPUT, SAID TRANSISTOR OSCILLATOR COMPRISING A POWER TRANSISTOR HAVING EMITTER AND COLLECTOR ELECTRODES CONNECTED ACROSS SAID INPUT AND HAVING A BASE ELECTRODE, A FIRST TRANSFORMER HAVING A PRIMARY WINDING CONNECTED IN SERIES WITH SAID POWER TRANSISTOR EMITTER AND COLLECTOR ELECTRODES ACROSS SAID INPUT, SAID FIRST TRANSFORMER HAVING A SECONDARY WINDING CONNECTED ACROSS SAID RECTIFIER-FILTER AND A FEEDBACK WINDING CONNECTED ACROSS SAID POWER TRANSISTOR BASE AND EMITTER ELECTRODES AND ORIENTED FOR PROMOTING CURRENT BETWEEN SAID POWER TRANSISTOR BASE AND EMITTER ELECTRODES WHENEVER CURRENT IN SAID PRIMARY WINDING IS INCREASING, MEANS CONNECTED SERIALLY WITH SAID FEEDBACK WINDING ACROSS SAID POWER TRANSISTOR BASE AND EMITTER ELECTRODES FOR PREVENTING PARASITIC OSCILLATIONS IN SAID FEEDBACK WINDING FROM INITIATING SAID PRIMARY WINDING CURRENT, A COMPARATOR TRANSISTOR HAVING COLLECTOR, EMITTER AND BASE ELECTRODES, MEANS FOR PRODUCING A STABILIZED DIRECT-CURRENT REFERENCE VOLTAGE, SAID REFERENCE VOLTAGE PRODUCING MEANS BEING CONNECTED ACROSS SAID COMPARATOR TRANSISTOR BASE AND EMITTER ELECTRODES AND ORIENTED FOR PROMOTING CURRENT BETWEEN SAID COMPARATOR TRANSISTOR BASE AND EMITTER ELECTRODES, AN OUTPUT VOLTAGE SENSING CIRCUIT CONNECTED ACROSS SAID OUTPUT AND HAVING AT LEAST A PORTION CONNECTED IN SERIES WITH SAID REFERENCE VOLTAGE PRODUCING MEANS ACROSS SAID COMPARATOR TRANSISTOR BASE AND EMITTER ELECTRODES FOR OPPOSING SAID REFERENCE VOLTAGE BY A DECREASING AMOUNT AS SAID LOAD VOLTAGE DECREASES, AND A SECOND TRANSFORMER HAVING A PRIMARY WINDING CONNECTED SERIALLY WITH SAID PORTION OF SAID OUTPUT VOLTAGE SENSING CIRCUIT AND SAID REFERENCE VOLTAGE PRODUCING MEANS BETWEEN SAID COMPARATOR TRANSISTOR BASE AND EMITTER ELECTRODES, SAID SECOND TRANSFORMER HAVING A SECONDARY WINDING CONNECTED SERIALLY WITH SAID COMPARATOR TRANSISTOR EMITTER AND COLLECTOR ELECTRODES ACROSS THE BASE AND EMITTER ELECTRODES OF SAID POWER TRANSISTOR AND ORIENTED FOR STARTING CURRENT THROUGH SAID POWER TRANSISTOR BASE AND EMITTER ELECTRODES WHENEVER CURRENT THROUGH SAID SECOND TRANSFORMER PRIMARY WINDING STARTS TO INCREASE.
